Airway implant and methods of making and using

Abstract

A system and device for maintaining and / or creating patency in airways is disclosed. The methods of using the system and device are also disclosed. The system includes a power source that energizes a electro-active polymer implant. The energized polymer implant provides stiffness and shape to the airway, thereby minimizing collapse or deformation of the airway. A method of making the device is also disclosed.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The invention relates to the systems, devices and methods for creating and / or maintaining airway patency, for example, for treating snoring and / or sleep apnea. [0003] 2. Description of the Related Art [0004] Snoring is very common among mammals including humans. Snoring is a noise produced while breathing during sleep causes vibration of the soft palate and uvula. Not all snoring is bad, except it bothers the bed partner or others near the person who is snoring. If the snoring gets worst overtime and goes untreated, it could lead to apnea. [0005] Those with apnea stop breathing in their sleep, often hundreds of times during the night. Usually apnea occurs when the throat muscles and tongue relax during sleep and partially block the opening of the airway. When the muscles of the soft palate at the base of the tongue and the uvula relax and sag, the airway becomes blocked, making breathing labored and noisy and even s...

AI Technical Summary

Benefits of technology

[0018] A new type of implant to treat patients with snoring and / or apnea is disclosed. An electroactive polymeric (EAP) device can be inserted in the soft palate and / or sidewalls of the patient's airway. The polymeric implant can have a very low stiffness under normal conditions. When the polymeric device is energized, the polymer can become stiff and tend to deform. The polymeric device, in its energized state, can have the ability to support the weight of the soft palate and sidewalls of the patient. When the charge is removed, the polymeric device can become soft and not interfere with the patient's normal activities like swallowing and speech.

[0022] One or more implants can be placed in the soft palate, sidewalls of the airway, around the trachea, in the tongue, in the uvula, or in combinations thereof. The implant can have lead wires (e.g., anode and cathode) attached to the surfaces. The lead wires can be connected to an induction coil. The induction coil can be implanted in the roof of the mouth. The patient can wear a specially fitted retainer type of device before going to bed every night. The retainer can have an induction coil, a circuit and a battery. When the patient wears the retainer, the induction coil in the retainer is aligned with the induction coil that is implanted in the roof of the mouth. The energy can be transmitted through the tissue and to the coil that is in the roof of the mouth. The IPMC implant can be energized, deform and stiffen to provide support. Patient can relax and sleep without the worry of the airway collapse in their sleep. In the morning when the patient wakes up, the patient can remove the retainer and place the retainer on a charging unit to recharge the battery.

Problems solved by technology

When the polymeric device is energized, the polymer can become stiff and tend to deform.
